Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 12 - 15; Dorsal soft rays (total): 12 - 14; Anal spines: 3; Anal soft rays: 7 - 9.

Found in moving water of inshore rocky reefs. Juveniles may ascend rivers and return to sea to spawn. Protandrous, sex change happens after maturation at age 2 (Ref. 36558). Spawning occurs during winter, in deeper rocky reefs or inshore areas. Predaceous, feeding on zooplankton at an early age and on small fish and shrimps as adults (Ref. 12497). Utilized as a food fish (Ref. 559). Family placement uncertain (Ref. 1830). Used in Chinese medicine (Ref. 12166).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Males mature at age 2 years, becoming females when older (Ref. 36558). Juveniles may ascend rivers migrating to the sea to spawn (Ref. 36558).

Estimates based on models

Preferred temperature (Ref. 123201): 12.7 - 26.3, mean 22.4 °C (based on 180 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01259 (0.00881 - 0.01800), b=3.02 (2.92 - 3.12), in cm total length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.3 se; based on diet studies.

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (K=0.14-0.2; tm=2; Fec=1,726,242).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (52 of 100).

Climate Vulnerability (Ref. 125649): Moderate to high vulnerability (54 of 100).

Price category (Ref. 80766): Very high.

Nutrients (Ref. 124155): Calcium = 16.5 [8.1, 32.0] mg/100g; Iron = 0.471 [0.277, 0.738] mg/100g; Protein = 20.1 [19.0, 21.0] %; Omega3 = 0.212 [0.131, 0.340] g/100g; Selenium = 24.4 [12.4, 44.2] μg/100g; VitaminA = 24.7 [8.1, 76.3] μg/100g; Zinc = 0.756 [0.525, 1.096] mg/100g (wet weight); based on nutrient studies.
